COMMENTS

The square roots of these numbers have some interesting properties, e.g. sqrt(a(8))= 2.7272727272727236363636363636339393939393939361616161616...

FORMULA

a(n) = 9/121*100^n+112/121-4/11*n. - Robert Israel.

a(n)= 102*a(n-1) -201*a(n-2) +100*a(n-3). G.f.: -(1-94*x+129*x^2)/((100*x-1) * (x-1)^2). [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Feb 14 2010]

MAPLE

a := proc(n) option remember: if n=0 then RETURN(1) fi: 100 * a(n-1) + 36 * n - 128 end: for n from 0 to 30 do printf(`%d, `, a(n)) od:

PROG

(PARI) { for (n=0, 100, if (n==0, a=1, a=100*a + 36*n - 128); write("b060183.txt", n, " ", a); ) } [From Harry J. Smith (hjsmithh(AT)sbcglobal.net), Jul 02 2009]
